States, traits, and the resting state EEG task aftereffect.
Article in International journal of psychophysiology : official journal of the International Organization of Psychophysiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHistorically, resting state electroencephalogram (rsEEG) measures have been considered indices of stable traits. However, recent research has indicated that rsEEG measures change after an individual has performed a task. These task aftereffects raise several questions regarding the task parameters needed to facilitate task aftereffects. This study aimed to set a foundation to answer these questions by creating a baseline of rsEEG changes observed within a healthy college aged sample before and after a classic cognitive task.
methodsThe sample consisted of 34 undergraduate students. rsEEG data were recorded in alternating states of eyes open and closed before and after a standard oddball paradigm task.
resultsResults indicated that timepoint (e.g. before and after study) had no significant effect or interaction with eye status when measuring peak alpha amplitude and frequency. When analyzing classic frequency bands, there was an interaction between eye status and timepoint for delta at electrode Fz, but no main effect of timepoint. This was the only interaction within the classic frequency bands. Frontal alpha and beta asymmetries shifted rightwards after the task, but had fair to poor reliability. Theta/beta ratio was significantly higher after the task.
conclusionsTheta/beta ratio was the only measure that met criteria for both a good experimental dependent variable and stable individual difference variable due to its high reliability. To our knowledge this is the first time these common rsEEG variables have been simultaneously assessed for consistent within-subject effects and reliable between-subject differences.
